I Fig. 2 I '2 l'amj I NVENTOR United States Patent EXERCISING DEVICE FOR LUNGS AND DIAPHRAGM Charles J. Ozment, St. Louis, Mo. ApplicationSeptember 5, 1952, Serial No. 308,027 1 Claim. (Cl. 84-466) The presentdevice relates to an exercising device for lungs and diaphragm and itconsists in the combinations, constructions and arrangements of partsherein described and claimed.

Generally there is provided an exercising device for the lungs,diaphragm and muscles relating thereto which device is particularlyuseful for athletes, singers and the like. The device consistsessentially of a hollow cylindrical tube having a closed wall at one endthereof and an integrally formed mouthpiece at the other end thereof.Along one side of the device there is arranged a series of progressivelysized openings each of which is surrounded by an integrally formedannular protuberance. The fingers of the user may be placed over theseprotuberances and the user then attempts to force air into the interiorof the device allowing selectively one or more fingers to be removedfrom such protuberances so as to allow a greater or lesser escape of airfrom the interior of the device. The pressure thus applied to the devicein varying amounts will act to exercise the muscles controlling thelungs and diaphragm of the user.

It is accordingly an object of the invention to provide a device of thecharacter set forth which is simple in construction, inexpensive tomanufacture and yet etfective and eificient in use.

Another object of the invention is to provide, in a device of thecharacter set forth, novel means for controlling the escape of air froma hollow cylinder forming a part of the invention.

A further object of the invention is to provide a device of thecharacter set forth which lends itself to simple manufacture by moldingor the like from a single piece of metal or plastic material.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawing, in which:

Figure 1 is a plan view of an embodiment of the invention,

Figure 2 is a side elevational view thereof,

Figure 3 is a sectional view taken along line 3-3 of Figure 1, and

Figure 4 is an enlarged sectional view taken along line 4-4 of Figure 3.

Referring more particularly to the drawing, there is shown therein adevice of the character set forth comprising an elongated hollowcylindrical body 10 having a closed end wall 11 at one end thereof andhaving integrally formed at the other end thereof a mouthpiece 12.

A series of openings 13, 14 and 15 is formed in one side of the body 10and each has an annular protuberance 16, 17 and 18 respectivelysurrounding the same and formed integrally with the body 10.

In operation, it will be apparent that the user of the device will placethe mouthpiece 12 in his mouth and then place his fingers upon theprotuberances 16, 17 and 18 and thereupon will attempt to blow into thebody 10 of the device. In order to exercise the muscles controlling hisdiaphragm and lungs, the user may then allow one or more of his fingersto move away from one or more of the protuberances 16, 17 or 18 as thecase may be to thus allow the escape of a certain amount of air thusbeing applied by his lungs and diaphragm to the interior of the body 10.It will be noted that the openings 13, 14 and 15 are of different sizesthus making it possible to secure a relatively accurate control of theamount of air which is allowed to escape from the body 10 at any giventime by allowing air to pass from one of the openings 13, 14 or 15 orfrom two or more of the same thus securing a great many combinations.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claims.

What is claimed is:

An exercising device for lungs and diaphragm comprising a hollowelongated, substantially cylindrical body, a circular end wallintegrally formed at one end of said body, a substantiallyfrusto-conical enlargement integrally formed at the other end of saidbody and providing a mouth piece, said body having a series ofdiiferently sized openings formed in one side thereof, said openingsbeing substantially cylindrical, and annular protuberances extendingfrom said body, each of said protuberances surrounding one of saidopenings, each of said protuberances at the upper end thereof having asubstantially frusto-conical enlarged bore communicating with the upperend of its respective opening.
